Six Sigma today is used by many corporations today,
and around the world. Identification and selection of Six Sigma projects is
often discussed. The origins of Six Sigma comes from the Greek alphabet used to
denote standard deviation, a statistical measurement of variation, the
exception to expected outcomes. (Thomsett, 2005)
Six Sigma concept can being with a
process called Business Process Management (BPM) which helps design,
communicate, and improve systems. The use of flowcharts and Gantt charts, and
MS Project charts help to communicate the intent of project managers.
Real Option Analysis is one method
that can improve the value of the project by considering the various kinds of
risks. Some companies use Six Sigma to reduce risks in projects. (RK Padhy, Dec 2011. Vol. 29, Iss. 8; pg. 1091) The major issues
addressed are quality control in an organization. People have argued that many communities can benefit from city
leaders that consider using Six Sigma’s operating model to help with improving
the way local governments are operated. “With lean Six Sigma implantation,
streets of Irving, Texas are repaired in less than 4 weeks compared to 16
weeks. When the employees of the city government have teams consisting of Six
Sigma members the implementation of lean Six Sigma has yielded positive results
in all areas for the city. (Brandt, Jul 2011. Vol. 43, Iss. 7; pg. 50, 3 pgs) This city used “lean
Six Sigma to attain results such as a drop in the crime rate, a vibrant local
economy, opening of a new convention center, and the creation of 3,000 new
jobs.” That shows us that there can be positive results by seeing cities
implementing Six Sigma methodology.
In
this economy may companies are turning to “Six Sigma models because it provide
various kinds of sustainability to companies in terms of quality enhancement,
zero defect level, market share enhancement, optimal production level, and
financial returns.” (Abdullah, May/Jun 2011) The reason companies use Six Sigma
is that it is a quality management, total quality management, zero defect
level, lean management, continuous improvement and Six Sigma has evolved from
programs at Lockheed, IBM, and Motorola in the 1980’s when they were called
only Zero Defects, and High Reliability programs. They have been initiated by
large corporations including: 3M, Merrill Lynch, Bank of America, Amazon.com,
DHL, SGL group, dell, Ford Motors, DuPont, McGraw Hill, and many others (Abdullah, May/Jun 2011) because of the
difficulties that small companies have in implementing many of the Six Sigma
concepts. The is Six Sigma for Quality Management, Sustainability, which
involves the implementation of proven quality principles, techniques, people, capital resources, natural resources,
environment, and institution. 3M adopted
Six Sigma to attain environmental stability during the course of implementation
of Six Sigma in a company utilizes the technique of data collection, and data
analysis. This will help with the core objective of Six Sigma which is to
improve on competition, zero defect level detections to help improve financial
success. . (Abdullah, May/Jun 2011)
In
the work environment, relationships are important to structure, communications,
and morale of any company. Establishing a continual improvement system is
essential to the
continued survival of any corporation.
The four loops in Figure 1 represent data analysis
supporting:
* Lean methods for sustaining the current process
(left loop).
* Process monitoring and corrective action to
return deviation to nominal requirements (bottom loop).
* Design for breakthrough improvement based upon key
system relationships (right loop).
* Conceptual research and profound knowledge for
organizational growth (top loop).
(Duffy, Milwaukee: May 2011.)
I found that the overlapping structure of a company
is well illustrated below to show how all the elements of an organization are
interdependent on each, like well-oiled gears in a factory.
Through
continuous improvement in an organization as a system, there will be long-term
success due to the interaction of processes across the complex systems in a
large corporation. This methodology of implementation of Six Sigma will create
effective improvement in this ever changing global economy. (Duffy, Milwaukee: May 2011.)
We
have seen many examples of the success of the implantation of Six Sigma, but we
really don’t understand what it is. According to the teaching of Dr. Walter
Shewer
•
Process Control;
•
Plan Do Check Act;
•
Common and Special Causes;
•
Improvement can be done project by project
•
Statistical tools
•
Hawthorne Plant Experiences
Other Definitions include:
•
Degree of variation;
•
Level of performance in terms of defects;
•
Statistical measurement of process capability;
•
Benchmark for comparison;
•
Process improvement methodology;
•
It is a Goal;
•
Strategy for change;
•
A commitment to customers to achieve an acceptable
level of performance
(Six Sigma,
NA)
According to many professionals Six Sigma methods
can be applied to various areas including:
Service, Design, Purchase, Production, IT, M&S,
HRM, Quality Depart, Administration, Management. There are Six Sigma
Initiatives that can integrate the below efforts.
(Six Sigma,
NA)
In Six Sigma there different methods of change
management for an organization,
·
Activity Centered programs – The pursuit of
activities that seem good, but don’t contribute to the bottom line.
·
Result Oriented programs – There focus is on
achieving specific, measurable, operational improvements in a few months.
·
Examples of specific measurable goals:
·
Increase yield, reduce delivery time, increase
inventory turns, improved customer satisfaction, reduce product development
time.
Many people don’t understand the
fact that Six Sigma is a problem-solving methodology for improving business and
organizational performance. There are
phases to Six Sigma for performance, improvement, deployment, and organization,
according to (Gygi, 2006)
A company that decides to implement it must realize that it is intense and rigorous;
it entails a thorough inspection of the way everything is done in a
corporation. Many times work in a department is performed incorrectly. Six
Sigma brings a quality-improvement methodology to a company. Through a great
deal of effort, discipline, and hard work Six Sigma will bring improved
performance, happier customers, lower costs, and success. (Gygi, 2006)
Management
system orientation can produce management results with a clear value
proposition and (ROI), top commitment, accountability, and customer focus. (Gygi, 2006)
A great deal of statistical
analysis is used in Six Sigma to identify the areas of a company that need
improvement. There is the application of
zero defects in Six Sigma which recognizes the size, or complexity of a
company, and how they are irrelevant for successful implementation.
Six Sigma applies a scale to characterize
quality control in company’s final products, services, and transactions,
especially when safety or human life is involved. (Gygi, 2006)
There is used a Sigma Scale as
illustrated below:
Sigma Percent Defective Defects
per Million
1 69% 691,462
2 31% 308,538
3 6.7% 66,807
4 0.62% 6,210
5 0.023% 233
6 0.00034% 3.4
7 0.0000019% 0.019
There are essentials of Six Sigma
besides the statistical aspects. The project methodology of (DMAIC) is
Define-Measure-Analyze-Improve-Control which is applied to improvement projects
that are managed to financial targets. There are various domains of activity:
Thinking, processing, designing. Six Sigma requires energize thinking, an open
mind by the corporate management, a thirst for truth, and betterment. (Gygi, 2006) Many corporations
have set ways of doing things. There will be initial reluctance by many
corporate management structures, resistance to implement changes that can’t
alter the way older corporations fundamentally run. It will often meet with
resistance by the corporate structure, if the team of executives doesn’t
properly develop a deployment program. (Gygi, 2006)
There must be the following people
and departments as core team members: Six Sigma deployment leader, business
unit Six Sigma leaders, key executive representatives, functional
representative, human resources, finance, information technology, training, and
communications.
To solve problems the Six Sigma
way requires varying degrees of skill in applied statistics. That is where Master
Black, Black, Green, Yellow, and White belts are utilized. Each type of Belt
has varying degrees in expertise in the implementation of the Six Sigma
process. The S.S. Black Belt would be considered the master of statistical
problem-solving. Lesser degrees of skill are defined including Blue Belt, Brown
Belt, and White Belt. This is derived from the various belts in Karate or Tae Kwon
Do which are martial arts disciplines.
There is an understanding and
enacting the breakdown strategy with the various teams who have varying levels
of Six Sigma expertise. Going from the objective, phase, output areas of a
project include, product returns, customer complaints, accounts receivables,
cycle time, ineffective of defective services, yield and subsequent rework,
capacity constraints, and excessive inventory levels. All of these areas can be broken down into areas
of concern in any organization, which requires structure, and a method of
approach.
The approach for dealing with
issues needs statistical data, data mining will give insight into analyzing how
each sector, and function in a corporate structure functions. (Brandt, Jul
2011. Vol. 43, Iss. 7; pg. 50, 3 pgs) There is a process
management summary that will take the data accumulated and implements in a
process review. A process control plan will be implemented by the Six Sigma process
to create a complete picture of all possible inputs, outputs, and activities
for a single process. (Gygi, 2006)
pg 230.
The various reports tools used in
Six Sigma projects that are available are generic reporting tools, integrated
tools, and balanced scorecards.
There is a timeframe for training
people in Six Sigma, with a series of lectures, video case studies,
experiments, workshops, exercise, defined projects, presentations, and homework for all those
learning Six Sigma. Over a span of 5 weeks or more of training, managers can
learn the detailed aspects of implementing Six Sigma. There various topics
aforementioned in the paper that goes over team roles, presentation skills,
project management skills, group techniques, quality, pitfalls of quality
improvement project, project strategies, and Minitab 16 introduction; which is
one of many programs used for charting in project management. (Six Sigma,
NA)
I shall conclude with the fact
that communications is of paramount importance with the implementation of Six
Sigma. If there is no or poor communications between all the employees in the
target company, then Six Sigma will be very difficult to implement. Because
there is so much literature to implement the Six Sigma Tools and Techniques,
high level managers who implement the various phases from:
The Define phase, the Analyze
phase, The Improve Phase, The Control Phase are all key elements to successful
lean manufacturing, significant cost saving, and better productivity for a
company that properly implements the methodology that Six Sigma provides to a
corporation in today’s global marketplace. (Pyzdek, 2003)
